"I'm not really sure why you would want to purchase the SFM-1000 fan mounts if your able to purchase the anti vibration mounting kit for just a few euro's more. You get so much more for only a couple of euro's more. The Anti vibration mounting kit is a nice addition to the line of products that Nexus currently has to offer. There are enough components included that are well worth the money. The fan mounts do the trick if you have a fan that makes a vibrating noise, the same for the hard drive mounting grommets. If your looking for a bunch of anti vibration mounting components for a decent price? Than this is the way to go."
